siderable wheat shipments from the United 

 States. 



As attention has been drawn to the variability 

 of the crops of the Argentine and Canada when 

 compared with that of the United States, some 

 detailed consideration of the yields over a series 

 of years is necessary. Again making use of the 

 returns issued by the International Institute of 

 Agriculture during the period 1901-10, the 

 highest yield per acre for wheat in the Argentine 

 is that of 1907 returned at 12J bushels per acre. 

 Once during the decade the yield has fallen to 6£ 

 bushels per acre, or 48 per cent, below the return 

 of the best year. One year it was 33 per cent, 

 below, and two years 28 per cent. With regard 

 to Canada the best year was 1902, with a 

 yield of about 23 bushels per acre. In one 

 year the yield dropped to 38 per cent, below 

 1902 ; in 1910 it fell 34 per cent, below, and in 

 I 9°4. 33 P er cent. With regard to Australia, 

 the best year was 1909, with a yield of nearly 

 13 bushels. Excluding 1902, when the crop was 

 practically a total failure with a yield of only 

 2\ bushels, in 1901 the yield was 44 per cent. ; 

 in 1907, 39 per cent. ; and 1904, 36 per cent, 

 below 1909. With regard to India and Russia, 

 the returns do not show so great a variation. 

 In India two years are 22 per cent, below the 

 maximum of 12 bushels recorded in 1910, and
